. but they seem to be quite optimistic they're moving towards something and a big endorsement, this earlier today from the top negotiator democrat in the senate, harry reid. a lot of moving parts. trying to get a hold on t. and talk about republicans. do we know where they stand on the approval of this deal? >> reporter: yeah. that is a big question, because the house republicans, you saw just how hard it was for the house republican leadership to get their own bill through the house, and to get their own members onboard for this deal. talking about a compromise, you can only guess that might be even a tougher sale, possibly. we haven't heard yet from house speaker john boehner or house leadership and where they stand on things. we know, though, however, we are told by a top senate republican leadership aide that they're not there yet and still working. so it seems like they're still working on the deal. clearly, not at a place harry reid is at this point and that's a big question of where are republicans going to stand on this? are they going to endorse it and what their issues are with it. don?
